Types 1xy (milling cutters), 2xy (drills), and 5xy (turning tools) are
calculated according to the same scheme.
Several entries exist for the geometric variables (e.g. length 1 or
radius). These are added together to produce a value (e.g. total length
1, total radius) which is then used for the calculations.
